The official Malaysia Airlines website has been hacked by a group claiming to support the terror group Islamic State, also called ISIS.

The airline's site was changed, at first displaying a message saying "404 - Plane Not Found'' and that the site was "Hacked by Cyber Caliphate,'' with a photo of one of the airline's Airbus A380 superjumbo jets. The browser tab for the website said "ISIS will prevail.''

The Malaysia Airlines homepage later changed to a black background featuring an image of a lizard in a top hat complete with monocle. The Islamic State reference was removed and the claim of responsibility changed to "Lizard Squad - Official Cyber Caliphate,'' with a link to the group's Twitter account.

Malaysia Airlines is trying to recover from twin disasters last year, including the disappearance of Flight 370 over the Pacific and the downing of Flight 17 over Ukraine.

The airline released a statement confirming the hacking but called it a "temporary glitch'' that did not affect passenger bookings.

The Lizard Squad last year claimed it was behind attacks on Sony's online PlayStation network and Microsoft's Xbox site.
